been wondering how to get lubricant. for electric engines considering it still requires heavy oil? which is behind a tech requiring utility science? which require
flying robot frame which retquires electric engines thus requiring lubricant?

You are correct. Looks like I made a boo boo. Technically possible to leverage other planets to get the science you need. But I'm going to push out a fix. Thanks for your input

I updated the research. Removed Production and utility science as a requirement. Now you can get the asphalt-and-concrete research to get light-oil akylation recipe.

Big mistake on my end. Sorry for the inconvenience, Thanks for letting me know. Hope you've been enjoying my mod otherwise.
